Ν= c/λ

λ= 486 nm * ( 1 m / 1x10^9 nm) = 4.86 x10^-7 m 

v= (3.00 x 10^8 m/s) /  (4.86 x10^-7 m) 
v= 6.1728395x 10^14 s^-1
= 6.14 x10^-14 Hz

Is a type of physical weathering
mash [69]

There are two main types of physical weathering: Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart. Exfoliation occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.

The structure of copper is described as a lattice of positive ions in a 'sea of electrons'.
seropon [69]

Answer:

A

Explanation:

Metal atoms are held together by metallic bonds. The metallic bonds are composed of a lattice of positive ions in a 'sea of electrons'.

The metal atoms are held together by strong electrostatic attraction between the positive ions and the 'sea of electrons' leading to high melting point of metals including copper.

Similarly, when a metal undergoes stress, the layers of the metal roll over each other but the lattice remains in place. Hence for metals such as Copper, layers of atoms in the lattice can slide over each other thereby making the metal malleable.

Metals oxidize by electron loss. Since Copper is metal, it can also be oxidized to form copper ions by loosing electrons.

A particular forest is 10,000 acres. Determine its size in hectares. (1 hectare = 2.47
igor_vitrenko [27]

Taking into account the change of units, a particular forest is 4,048.58 hectares.

<h3>Definition of rule of three</h3>

The rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, the direct rule of three must be applied using the following formula, where a, b and c known data and x the variable to be calculated:

a ⇒ b

c ⇒ x

So: x= (c×b)÷ a

The direct rule of three is the rule applied in this case where there is a change of units.

<h3>Size in hectareas</h3>

To perform in this case the conversion of units, you must first know that 1 hectare = 2.47 acres.

So, the rule of three can be used as follow: if 2.47 acres is 1 hectare, 10,000 acres equals how many hectares?

2.47 acres ⇒ 1 hectare

10,000 acres ⇒ x

So: x= (10,000 acres ×1 hectare)÷ 2.47 acres

Solving:

<u><em>x= 4,048.58 hetares</em></u>

In summary, a particular forest is 4,048.58 hectares.
